Pressure transmitter for industrial pressure monitoring up to 1000 bar

Precont PU4SM

Pressure transmitter for industrial pressure monitoring in gases, vapors, liquids and dusts, with ranges from 400 mbar to 1000 bar, IP69K/IP67 protection and 4…20 mA FSK, RS485 Modbus®-RTU, IO-Link® or 0...10 V outputs.

Introduction

Demanding pressure points in machinery, hydraulic systems or process plants need stable readings without slowing down commissioning. This transmitter monitors, controls and continuously measures pressure in gases, vapors, liquids and dusts, with measuring ranges from 400 mbar to 1000 bar and accuracy up to ≤ ±0.15% FSO.
 
A robust welded stainless steel housing supports reliable use in tough industrial environments. Ingress protection (IP69K/IP67), process temperatures up to +125 °C and resistance to high shock and vibration loads make it well suited for applications where moisture, cleaning or mechanical stress are part of daily operation.
 
Flexible outputs help the device fit into existing automation concepts. Depending on the version, it provides 4…20 mA FSK, RS485 Modbus®-RTU, IO-Link® or 0...10 V, with response times down to ≤ 2 ms. Flush diaphragm process connections also support integrated cleaning for viscous or frequently changing media.
